The exceptional versatility of sulfones has been extensively exploited in organic synthesis
across several decades. Since the first demonstration in 2005 that sulfones can participate …

One of the simplest organic functional groups, the alkyne, offers a broad canvas for the
design of cascade transformations in which up to three new bonds can be added to each of …

Thiyl radicals have been used by nature in a broad range of biochemical processes. For
instance, thiol residues play an important role in many enzymatic processes as illustrated by …

A new coupling protocol has been developed that allows the union of vinyl sulfones with
photoredox-generated α-amino radicals to provide allylic amines of broad diversity. Direct C …

A new α‐C (sp3) H alkynylation of unactivated tertiary aliphatic amines with 1‐iodoalkynes
as radical alkynylating reagents in the presence of [Au2 (μ‐dppm) 2] 2+ in sunlight provides …

C (sp3)–C (sp) bond formations are of immense interest in chemistry and material sciences.
We report herein a convenient, radical-mediated and catalytic method for C (sp3)–C (sp) …

Abstract A novel C− C bond‐forming strategy employing manganese‐catalyzed ring‐
opening of cyclobutanol substrates, followed by cyanation or ethynylation, is described. A …

The alkynylation of radical intermediates has been known since a long time, but had not
been broadly applied in synthetic chemistry, in contrast to the alkynylation of either …

Iridium-and ruthenium-free approaches to protected allylic amines and alkyl nitriles under
photoredox conditions are reported. An inexpensive organic dye, eosin Y, catalyzes …

The chemistry of sulfones has been extensively studied and widely exploited in organic
synthesis for the past several decades, prompting several general reviews1±9 of the subject …
